本文旨在研究雙組輸出順向式轉換器交互穩壓率適合於低功率及成本效益的應用。本文中以共振重置順向式轉換器為例分析其動作狀態及各操作區間之數學模型。雙組輸出轉換器次級側的非理想參數是造成交互穩壓最重要之原因。本文中提出一新的設計方法滿足雙組輸出順向式轉換器輸出穩壓規格。進一步製作實驗電路以利實測波形與量測數據之探討。實驗結果驗證理論分析及提出使用飽和電感、加入假性負載等方式做為輕載調節策略。
關鍵字：雙組輸出順向式轉換器、交互穩壓、輕載、飽和電感、假性負載。

This dissertation aims to study the cross regulation of dual-output forward converters suitable for low-power and cost-effective applications. The circuit operation and mathematical model for the resonant resetting forward converter are derived and discussed in detail. Cross regulation between two output voltages are described in terms of circuit parameters with secondary-side parasitic considerations. A new design method is proposed in this dissertation to meet the given output regulation specifications for a dual-output forward converter. A prototype circuit is implemented and tested. The experimental results are shown to verify the theoretical analysis and the proposed design method when saturated inductor and dummy load are used to improve the light-load regulation.

Keywords: Dual-output forward converters, cross regulation, light-load, saturated inductor, dummy load.
